Denji is a teenager who lives his life as a Devil Hunter.

Aiming to pay off the debt he inherited from his father, he starts hunting devils for the yakuza with his buddy Pochita, a "Chainsaw Devil", while living a tragically poor life.

Just when things seem like they couldn't get any worse, Denji gets betrayed and killed by the yakuza. As Denji starts passing out, he hears someone calling from inside his head...
The yakuza won't be on your case 
if you wait until I've been buried, right?
لن يُطاردك الياكوزا إذا انتظرت حتّى أُدفَن، صحيح؟
Nach der Beerdigung verfolgen uns
die Yakuza ja nicht mehr.
Si creen que estoy en la tumba,
los yakuza ya no te perseguirían, ¿o sí?
La mafia no te perseguirá
si me dan por muerto y enterrado, ¿no?
Attends d’être enterré,
comme ça on te fichera la paix.
Se fizer isso depois que me enterrarem,
a Yakuza nem irá atrás de você, né?
Якудза ж и не заметят,
если ты могилу мою тайком раскопаешь.
